Letters Patent No. 66,320, dated Julyffi, 1867.

IMPROVEMENT IN THE MANUIGTURE 0F CLAY PIPES.

' TO ALL WHOM IT MAY ONCERN:

Be it known that I, HORACE A. GOODRCH, of Joliet, in the State 'ofIllinois, have invented certain' new and useful improvements inMachinery for the Manufacture of Clay Pipes; and I do hereby declarethat the following is a full, clear, and exact description of the same,reference being had to the accompanying drawings, malcinga part of thisspecification, in which- I Figure 1 is a top or plan view,

Figure 2 a front view, and I Figure 3 a vertical section.

l Like letters refer to the same parts in all of the figures.

Y The nature and objects of my invention consist in improving the mouldsor dies and plates of the box or machine 'usually placed below apug-mill for the purpose of forcing clay pipes out horizontally, byattaching the inner flange or gatherer to oneplate, and the outer ringor portion of the mould to another which is adjusty* able, and insupporting the front end ot' the screw or-beater byv a bridge so locatedas not to interfere with the action or operation of the screw or injurethe pipe. In the machines heretofore in use a large hole has been madein the front plate, and the internal liange or gatherer attached to theouter ring ofthe mould and inserted through the hole, whilcthe outer orfront end of the screw was not supported at all, by which arrangement itwas and is exceedingly difficult to keep the central part of the mouldor die in the centre of the pipe, and Yalmost impossible to centre itafter the clay was in the box, as the clay filled the space between theflange and the plate, and could only be overcome by prying out the mouldat the side and wedging it. By my improvements these dilliculties areall overcome, and the operation of the box and mould very much improved.

To enable others skilled in the art to make and use my improved machine,I will describe its construction and operation.V v- The box A is made ofiron, orother suitable material, and of the usual dimensions. The frontplate B is made to fit the end of the box, and `is fastened bybolts andlianches, substantially as shown. To this plate I cast or otherwiseattach a Harige,l C, which is suited to the sizeof the pipe in diameter,and projects about four inches, and is brought nearly to a sharp edgeb'y bevelling the outer side. This liange need not Vnecessarily goentirely aroundthe screw, asin some of the places tho box can be made toperform its ollioe. The outer face f of the plate B is smooth, andagainst this I placca smooth-faced plate, D, which is attached by thebolts b which pass through the platev B, fitting it closely, and throughthe plate D through holes which are about twice the size of the bolts,leaving a space for the plate D to be adjusted upon the bolts, so as tobe equidistant from the central part F of the mould at all points. Whenit is adjusted the nuts are screwed down so that it will remain asplaced. The central part gf the mould or die F is attached to the end ofthe screw or beater-shaft G, and may revolve with it. The screw orbeater-shaft is supported in the main by the elongated bearing H, sothat the bridge a will not -require to be made of. great strength. Thebridge a is placed across the opening in the plate B, and supportsthescrew G. It is placed between the revolving die and the screw orbeater,A and the lliiring spacegbetween the ring Il and the revolvingcentre or core F being so arranged that while it increases in size itdiminishes in the distance between the two. The pipe is actually formedafter passing the bridge, so that it does not injure the pipe, and addsgreatly to the steadiness of the machine, and facilitates keeping themould in proper position. And by this arrangement of the plates andmould or dies I am enabled to change them in size with facility, andwithout disturbing the clay in the box.- The screw'is operated by thewheel I, and an ordinary pug-mill placed over or at the side ofthe boxA,'as it is` immaterial whether the clay pipe is -e forced out in avertical or horizontal position. Its operation will be understood fromits construction. L What I claim as new and as my invention, and desireto secure by Letters Patent, is-

1. The bridged., when llodatcd between the screw or feeding portion ofthe shaft G and the revolving core F of the mould in a clay-pipemachine, substantially as and for the purposes specified.

2. The plate B, when provided'with a gathering flange, C, projectinginwards and permanently attached, substantially as set forth.

`3. The plate D, when provided with the outer portion E of the mould,and made adjustable by means of the holes and bolts l), substantially asdescribed. i Y H. A. cooperen-- Witnesses:
